Drywall Weight Calculator

Plan crew sizes and delivery logistics by estimating the total drywall weight. Enter the installed area and thickness; the calculator multiplies by an industry-average 2.75 pounds per square foot at 1/2-inch thickness to project total load.

Total square footage of drywall installed. Multiply sheet length by width and number of sheets, then sum the areas.
Panel thickness in inches. Common sizes are 0.5 in for interior walls and 0.625 in for Type X fire-rated boards.

Verify weights with manufacturer data for precise needs.

Examples

  • 350 sq ft of 5/8 in Type X panels ⇒ 1,203 lb
  • 120 sq ft of standard 1/2 in drywall ⇒ 330 lb

FAQ

Where does 5.5 come from?

It's the weight per square foot per inch based on 2.75 lb for 1/2 in.

Does moisture affect weight?

Yes, damp drywall can weigh more than estimated.

Can I use metric units?

This calculator uses imperial units only.

Is the relationship linear with thickness?

Yes. Doubling the thickness roughly doubles the weight when material density stays constant.

How many people do I need to lift heavy boards?

Most safety guidelines recommend at least two people or a panel lift for sheets heavier than 70–80 pounds. Use the calculator's output to assess handling needs.

Additional Information

  • The result is expressed in pounds. Divide by 2.205 to convert to kilograms for metric planning.
  • Weight varies by manufacturer and moisture content; check product data sheets for precise numbers before engineering decisions.
